What is a therm unit used for?

Therm is a non-SI energy unit mainly used to measure natural gas consumption in residential and commercial settings.

Why convert therm to Hartree energy?

Converting therm to Hartree energy connects practical natural gas energy values with atomic-scale energies used in quantum chemistry and physics research.

Are there any challenges with this conversion?

Yes, the differences in therm definitions and the extremely small size of Hartree energy compared to therm make the conversion and interpretation more complex.
